Domestic residential energy consumption accounts for approximately one third of total energy consumption.
The constant and progressive rise in energy costs has changed the reference scenario with the consequent development of normative acts and initiatives to support energy efficiency.
The most important legislative provision on energy saving is certainly Directive 2002/91/EC concerning energy efficiency in building construction.
Thereafter, Italian legislative decree 192/2005 as amended by legislative decree 311/2005 introduced the concept of energy certification of buildings.
Consequently, the design of air conditioning systems has led to the gradual and constant reassessment of centralised systems for more rational use of conventional energy combined with the exploitation of alternative energy sources.
SATK50-60 series heat interface units are devices that combine the benefits of a centralised system in terms of energy efficiency and ease of maintenance with the freedom of independent temperature control typical of a domestic boiler. The heat interface units are also fitted for metering of the tenant heat and water consumption. The production of domestic hot water occurs instantaneously in the immediate proximity of the place of use, dispensing with the need for frequently bulky storages and complex recirculation circuits. SATK50-60 series heat interface units are compact in size and can be recess mounted in communal spaces thereby avoiding the need to occupy space inside apartments.
